Application filed January 22, 1916. Serial No. 73,626.

To all whom, it may concern Be it known that I, DANIEL E. MORGAN, a citizen of the United States, residing at North East, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Plow-Standards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plows, and more particularly to land breaking plows, and

. the primary object of the invention is to provide a yieldable standard for supporting the beam wheel of a breaking plow.

A further object of this inventionhs to provide a standard as specified which includes a fiat bowed spring, which is connected to the axle of the plow wheel and to a rigid support, and further to provide a vertical standard which is slidably connected to the forward end of the beam of the plow and is normally held against vertical movement by a catch, from which it is disengaged when the plow wheel. engages a rock, high place in the ground, or the like, for permitting the wheel to move upwardly independent of the plow beam, thereby limiting the liability of the drawing of the plow point out of the ground and either plowing a shallow place in the furrow, or completely skipping a part of the ground which is to be broken or plowed.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a plow, showing the improved standard attached thereto, Fig. 2 is a side elevation of the improved standard, showing the same in a position after having been actuated by the wheels riding over a rock, and Fig. 3 is a section on the line 33 of Fig. 1.

Referring to the drawing, 1 designates a breaking plow of any ordinary construction, as an entirety, which has a beam 2 of the ordinary construction. The beam 2 has the usual type of breaking plow structure attached to its rear end which comprises a share 3 and a mold board 4.

The beam 2 has brackets 5 attached to its opposite sides adjacent its forward end.

The brackets 5 rigidly support vertical rods 6, which rods have their upper ends angled, as is shown at 7 and extending forwardlv from the upper ends of the vertical rods at right angles thereto. A shoulder 8 is formed upon the forward surface of the lower end of each of the vertical rods 5, and these shoulders 8 have their forward. surfaces rounded, as is clearly shown at 9.

The brackets 5 have vertical sockets 10 formed therein, in which is slidably seated the vertical rods or standards 11, the lower ends of which are connected to the axle 12, which supports the plow beam wheel 13. The vertical rods 11 extend slidably through brackets 14, which are attached to the lower ends of the rods or bars 6, and are adapted for engaging the shoulders 8, which shoulders act as a fulcrum for the vertical rods or bars 11. Bowed fiat springs 15 are secured to the lower ends of the bars 6 and to the axle 12, as is clearly shown in Fig. 1 of the drawing. The springs 15 yieldably hold the axle 12 and the standards 11 in their normal position, as shown in Fig. 1 of the drawing, at which time the upper ends of the standards or bars 11 are positioned beneath the under surfaces of the angled ends 7 of the bars 6, which angled ends form catches or stops for preventing vertical yieldable movement of the bars 11 and the axles 12 and wheel 13. When the wheel strikes a rock or other obstruction, as indicated at 17 in Fig. 2 of the drawing, it will force the wheel rearwardly, for a comparatively short distance, which will rock the vertical bars 11 on the shoulders 8 of the fulcrum, and move the upper ends of the bars from beneath the angled ends 7, which will permit the bars 11 to move upwardly, as is shown in Fig. 2 of the drawing, also permitting the axle 12 and wheel 13 to move upwardly, which allows the wheel 13 to ride over the obstruction 17 without raising the forward end of the plow beam'2, thereby eliminating the liability of the raising of the plow point or share 3 out of the ground which is being plowed or broken. Immediately after the wheel 13 passes over the obstruction the springs 15 will force it downwardly to its normal position, and cause the upper ends of the vertical bars 11 to move beneath the angled ends 7, which locks the vertical bars 11 against yieldable movement independent of the plow beam 2.

In reducing the invention to practice, cerby the lower end of said bar, means for preventing vertical movement of said bar independent of said beam, said bar adapted for movement out of operative relation with said last-named means upon pivotal movement of the bar, and a fiat bowed spring connected to the lower end of said bar for 1 automatically returning the bar to its normal position and into operative relation with said, last-named means.

2. The combination with an ordinary land breaking plow including a beam, of a bracket attached to said beam adjacent to its forward edge, a vertical bar slidably supported by said bracket for pivotal and ver: tical movement, a second bar rigidly carried by said bracket and having its upper end bent for engagement with the upper end of said slidable and pivotalbar for preventing vertical movement of said pivotal bar independent of said plow beam and bracket, a beam supporting wheel rotatably carried by the lower end of said slidable bar, said slidable bar being adapted for movement out of engagement with the angled end of said rigid bar upon pivotal movement of the slidable bar, for permitting of vertical movement of the slidable bar and the beam supporting wheel independent of the plow beam, and means for automatically returning said vertical bar and supporting wheel to their normal position.

3. The combination with an ordinary land breaking plow including a beam, of a bracket attached to said beam adjacent to its forward edge, a vertical bar slidably supported by said bracket for pivotal and vertimovement of the slidable bar and the beam supporting wheel independent of the plow beam, a flat bowed spring connected to the p lower end of said rigid bar and said slidable bar for automatically returning said slidable bar to its normal position.

In testimony whereof I afiix my signature in presence of two witnesses.

DANIEL E. MORGAN.
